Split MSAL (Global) and PCA-Specific Configuration

[fadidurah]

What Adding support for global configuration, where developers designate global fields that they'd want all PCA instances to have through a global configuration file. Refer to the design document PR below. https://identitydivision.visualstudio.com/DevEx/_git/AuthLibrariesApiReview/pullrequest/4763

Relies on: https://github.com/AzureAD/microsoft-authentication-library-common-for-android/pull/1726

Why At the moment, every PublicClientApplication (PCA) needs a configuration file to explicitly set all of its configuration fields, including fields that are not designed to be different across multiple PCA instances within the same application. A developer would need to create a different configuration file if they wanted to exclude a field from a PCA's configuration, and reapply whatever fields they wanted to keep.

How Creating a GlobalSettings class used to initialize the global configuration from a global configuration file that the developer passes in as a parameter. In this design, the global settings initialization is done before the PCA is created in the developer's app. Once initialization is done, the global settings will be available as a static singleton field, which can be used later by PCA instances to supply global fields as command parameters. These settings are called "Global" because as mentioned above, fields included in these files are not meant to be changed between different PCA instances within the same session.

Testing Added unit testing in this PR through GlobalSettingsPublicClientApplicationTest to check current implementation is not broken and new global field reading is being sent to PCAConfiguration correctly. Testing in common (see other PR).
